Did the SSR 5.3 have the 90mm intake? or the Envoy? I'm not aware if they did or not. Do you know where the engine came from? Can you just ask the guy what's up with it? If it has DOD you can tell my checking the lifters. If it has VVT, you can tell just by looking at the front cam sensor. The VVT ones are spaced out quite a bit further from non VVT.

EDIT: VVT also has a phaser and two sensors on front, not just the one.
